Answer:
A
Step-by-step explanation:
To calculate the slope m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 7) and (x₂, y₂ ) = (9, 1) ← 2 points on the line
m = =
=
Which is equivalent?

Answer:
The saucer's circumference is <u>25.12 centimeter</u>.
Step-by-step explanation:
Given:
Linda calculated that the saucer for her tea cup has an area of 50.24 square centimeters.
Use 3.14 for π.
Now, to find the saucer's circumference.
So, we get the radius first by putting the formula of area:
Area = 50.24 square centimeters.
Let radius be
As given we use 3.14 for π.
<em>Dividing both sides by 3.14 we get:</em>
<em>Using square root on both sides we get:</em>
Thus, the radius = 4 centimeters.
Now, to get the circumference we put formula:
Circumference = 25.12 centimeter.
Therefore, the saucer's circumference is 25.12 centimeter.
